The material of Headspace Vials is low extractable Borosilicate glass with low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Headspace Vials suitable for headspace analysis of volatile solids and gases.

A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.

The round-bottomed headspace vial distributes the internal pressure generated at high temperatures on the entire glass surface, and the beveled edge has a firm edge that can be pressed into the septum to achieve a more effective seal. The flat-bottomed sample bottle has a long neck and is suitable for use with headspace automatic sampling instruments

Aijiren provides one of the widest selections of Caps, Closures, and Lids available. Select from a wide variety of metal and phenolic, and polypropylene plastic bottle caps, vial lids, and other closures with an array of lining systems to fit your application and container. We also feature dispensing caps, hole caps, septa, tube caps and vial caps.

A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.

Headspace vials have different capacity specifications, including 6ml, 10ml, 20ml, etc. Use a standard sample vial to ensure sufficient headspace. Usually, the reserved volume should be at least 50% of the sample volume.

Headspace GC is a sample preparation method for determining volatile compounds in solid and liquid samples. Headspace sample vial is generally used for gas phase experiments.

Headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or with a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs.

Headspace vials can withstand the higher temperatures and internal pressures required for volatile gas analysis. The Color of headspace vials is divided into two kinds of brown and transparent, the brown vials can be protected from light, and the manufacturing process adopts the molding method, which has the characteristics of thick wall, high mechanical strength, and not easy to be broken.

20mm crimp-top headspace vials are a type of laboratory vials commonly used in gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) applications.
These vials are specifically designed for the analysis of volatile compounds in samples.
Headspace analysis is used when analyzing volatile or semi-volatile compounds that can be released from a solid or liquid sample into the gas phase.
This technique is particularly useful for samples that would be difficult to directly inject into a GC system or when analyzing volatile compounds in complex matrices.
